tcp remote ports question
Hello,
Most people know that you could go to a website like ipchicken.com to find out your ip and other browser environmental variables. On ipchicken.com, you can see your "remote port" also... I was under the impression that TCP/IP ports are always from 0-9999, yet the remote port listed is a 5-digit port. Not only that, but it changes every couple of seconds when I refresh.
I am connected to the internet via a cable modem with comcast as my ISP. I am getting the address via DHCP... The remote port is also showing up on access logs of devices that my computer logs onto in remote devices... what is this thing for and how is it different from TCP/IP ports?

So I request a webpage from port 80 (of the server) and send a "remote port" along with the packet so that server knows to send the information requested to my ip address at the "remote port"?
Does it change for every web page I request?

Yes, and Yes
Hi meuedyn,
Right, the HTTP server listens on port 80. However, your browser, and other client applications, send requests and receive responses on arbitrary high-numbered ports.
Cheers!
